Abstract

L'invention concerne un procédé et un dispositif de découpage de platines (19) dans un matériau en bande (5) progressant, par intermittence, à travers un dispositif de poinçonnage comprenant un tampon (17) monté tournant autour d'un axe (25) s'étendant perpendiculairement au plan d'acheminement du matériau, et une matrice montée tournante, le tampon et la matrice (14) prenant, par rotation synchronisée, et par rapport à une position de départ, des positions de coupe différentes, afin de réduire les chutes lors du découpage des platines. L'invention a pour but de permettre d'avoir des angles de rotation quelconques de l'outil, sans influencer défavorablement le transfert des platines, notamment profilées irrégulièrement, à un dispositif de transport. A cet effet, l'invention est caractérisée en ce que les platines sont réceptionnées, immédiatement après découpage, par un système de prélèvement de platines (20), et sont transférées, indépendamment de leurs positions de découpe respectives, toujours dans la même direction, du système de prélèvement de platine au dispositif de transport.
